This is an experiment with jQuery and Raphael.
Add this user script to Chrome or Firefox+Greasemonkey to install the Kraken. After downloading you can just drag and drop the file (Kraken.user.js) onto a browser instance. Then on ANY web page the key combo [cntrl]+[shift]+Z will summon the Kraken. Enter a jQuery selector into the input area, hit [enter], and then...
The Kraken be smackin' your DOM.
